PRACTICE DRUM.

Application filed October 30,` 1926. Serial No. 145,240.

This invention relates generally to the art of drums, and has moreparticular reference to a practicing device wherein the art of learningto play a drum may be satisfactorily practiced without the disagreeablenoise being created.

One of the main objects of the invention is to provide a practicedrumfwherein the drumming member may be readily raised or lowered aswell as adjusted to the proper angle similar to the elevation andangular position of a regular drum when in use.

A further and important object is to provide a practice drum of thischaracter that is extremely 'simple of construction, inexpensive ofmanufacture and one that is well adapted for all the purposes intended.

With the foregoing and other objects that will become apparent as thenature of the invention is better understood, the same comprising thenovel form` combination, and arrangement of parts hereinafter more fullydescribed, shown in the accompanying drawing and claimed.

In the drawing wherein like reference characters indicate correspondingparts throughout the several views:

Figure 1 is an elevation of my improved practice drum.

Figure 2 is a detail vertical section thereof taken substantially uponthe line 2-2 of Figure 1, and

Figure 3 is a horizontal section taken substantially upon the line 3-3of Figure 1.

Now having particular reference to the drawing. wherein there isdisclosed the most preferred embodiment of the invention with which I amat this time familiar, the practice drum consists of a circular plate 5having a central circular opening 6 surrounding which is a concentricchannel 7 formed in the outer face of said plate. Stretched over theopening 6 is a circular sheet of heavy rubber 8. the perimeter of whichis forced within the circularchannel '7 of the plate 5 and thereretained by a metallic ring 9 secured within the channel by screws orother like fasteners 10.

` At four equally spaced points upon the under side of the plate 5 andadjacent the outer edge thereof are hinge plates 11, the other plates ofsaid hinges overlapping the upper ends of supporting leg sections 12 towhich said hinge plates are pivotally conr nected as at 13. Said legsections 12 are in the form of Hat metal bars, and each has alongitudinal slot Miformed therein. Complemental to these leg lsections12 are other sections 15 that are slidably arranged upon the inner sidesof the uppermost sections and most sections by bolts 16 passing throughthe slots 14 in the sections 12 and upon the outer ends of which arethreaded Wing nuts 17. The extreme lower ends of the upper leg sectionskthat are adj ustably connected to said upper-` 12 are formed atopposite edges with guide lugs 18 that ride upon the edges of thelowermost leg sections 15 so that t-he sectionswill not move out oflongitudinal alignment.

The lower ends of the leg sections 15 are bentslightly outwardly as at18 so as to provide supporting feet, while all of said sectlons 15 areinterconnected by a pair of angularly formed brace bars 19-19 that are1n turn interconnected at their center as in Figure 3; Obviously byreason of the construction just described and disclosed in the drawing,I have provided a highly novel, useful and efficient practice drum thatmay be adjusted vertically, and that may be positioned at the desirableangle'so that the art of playing a drum may be easily learned.

The angular adjustment of the plate 5 is appreclab y small and isattained due tothe flexibility of the strips of metal that comprise theleg sections 12. This flexibility of the leg sections will permit aslight variation in t e radial distances.

Even though I have herein shown and described the invention asconsisting of a. certain preferred embodiment, it is to be understoodthat other forms may be had without affecting the spirit and scope ofthe appended claims.

I-Iaving thus described the invention, what I claim as new and desire tosecure by Letters Patent is i 1. In aA practice drum of the classdescribed, a flat circular wooden base plate formed with acircumferential channel in the upper face thereof inwardly of theperimeter of said circular plate, drumming material arranged over thecentral portion of the upper face of the base plate, the edge portion ofsaid drumming material being adapted for disposition in thecircumferential channel, and a metallic ring secured entirely within thechannel, and clamping the drumming material in a taut position.

2. In a practice drum of the class described, a fiat circular woodenbase plate formed with a circumferential channel in the terial in a tautposition, and a series of inde- 10 upper fece thereof inwardl of theperimpendently adjustable leg members hingedly eter of said circularplate, rumming matesecured at their upper ends to the bottom rialarranged over the central portion ofthe of the base plate adjacent theouter edge 5 u per face of the base plate, the edge portion thereof forsupporting the base plate in cero? said drumming material being ada tedtain angular positions. 15 for disposition in the circumferential c an-In testimony whereof I aix my signature. nel, a metallic ring securedentirely within the channel, and clamping the drumming ma JOSEPH J.STRAUB.
